Other Diagnostic Studies
Other diagnostics studies for dysphagia are as follows:[1]
Oropharyngeal Dysphagia
- Electromyography (EMG)
- Electroglottography (EGG) (records vocal fold movement)
- Cervical auscultation
- Pharyngeal manometry
Esophageal Dysphagia
- Esophageal manometry
- High resolution manometry
- Uses miniature, multichannel, water-perfused catheters[34] or solid-state catheters.[35]
- Pressures are recorded from up to 36 closely spaced sites along the esophageal body and across the gastroesophageal junction.
- A computerized interpolation technique then generates esophageal pressure isocontour lines, which are used to provide a three-dimensional pressure map of the entire organ.
- This technique has also been successfully applied to studies of the pharynx and upper esophageal sphincter.[36,37]
- In addition, highresolution manometry facilitates differentiation between a restrictive disorder and muscular weakness in the pharyngoesophageal segment,[39] and makes the precise pressure profile across the esophagogastric junction obvious, which enables improved visualization of the diaphragmatic component and of any hiatal hernia.[40]
- High resolution manometry
